Chapter 14: Q. 22 (page 1150)

In Exercises $21 - 24$ , compute the divergence of the given vector field.
$F (x, y, z) = y z \cos z i + (z - x) j + e^{x} y k$

Short Answer

Expert verified

The divergence of the given vector field is $0$

Step by step solution

01

Step 1

Think about the vector field,

$F (x, y, z) = y z \cos z i + (z - x) j + e^{x} y k$

Our goal is to determine the vector field's divergence.

Make use of the formula, $div F = \frac{鈭� F_{1}}{鈭� x} + \frac{鈭� F_{2}}{鈭� y} + \frac{鈭� F_{3}}{鈭� z}$

In comparison to the supplied vector, $F (x, y, z) = y z \cos z i + (z - x) j + e^{x} y k$ using the vector, $F (x, y, z) = F_{1} (x, y, z) + F_{2} (x, y, z) + F_{3} (x, y, z)$

So, $F_{1} (x, y, z) = y z \cos z$

$F_{2} (x, y, z) = (z - x)$

$F_{3} (x, y, z) = e^{x} y$

02

Calculation

Estimate $div F$

div F = \frac{鈭� F_{1}}{鈭� x} + \frac{鈭� F_{2}}{鈭� y} + \frac{鈭� F_{3}}{鈭� z}

$\frac{鈭�}{鈭� x} (y z \cos z) + \frac{鈭�}{鈭� y} (z - x) + \frac{鈭�}{鈭� z} (e^{x} y)$

$= 0 + 0 + 0$

$= 0$

Hence, $div F = 0$

Find the masses of the lamina:

The lamina occupies the region of the hyperboloid with equation $z^{2} + 4 = x^{2} + y^{2}$ that lies above and/or below the disk of radius 5 about the origin in the XY-plane, and the density function, 蟻(x, y,z), is proportional to the distance from the origin.
